Parallel/Series - Altoids tins and rubber caps. The AA batteries fit like 6 wide in a tin, and the rubber caps serve to hold the positive sides of the batteries from contacting the tins, shorting them out.

You use the tin for the neg side of each battery and run a wire for the pos sides up under the caps. Soldering the wire into a ring shape before you put it on, then putting a small spring or something inside the cap will make sure the wire retains contact.
